From a MyModernMet.com online article:
Since I work as a fine artist now, there are fewer commercial entities to please, so I’ve discovered something that should have been very obvious. If you want to engage the viewer, don’t tell them everything, encourage them to ask their own questions. An artist should not describe—he or she should interpret. If you design into your work a bit of mystery—areas where the viewer must “fill in the blanks”—you set up an unspoken dialog with your viewers and an emotional weight will begin to develop organically. This is just one example of course, but an important one.
Artist Thomas W. Schaller combines a passion for architecture and storytelling into emotional landscape watercolor paintings. Originally trained as an architect, he found himself drawn to images of the built environment and eventually left designing behind to pursue fine art on a full-time basis. His education places him in an ideal position for architecture painting. Schaller understands how to design structures and knows what attributes to include and what he should leave out. At the same time, he’s able to tap into the feelings we get from visiting a city—such as a sentimentality—to produce pieces that are both beautiful and alluring.
